Jing Wu Wen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Liquid crystal color switch and method of manufacture
    Patent number: 6950171
    Abstract: This invention involves one kind of liquid crystal color light switch, made especially from cholesteric liquid crystals. By changing the voltage applied, the reflection wavelength of the color light switch can be controlled, leading to a rapid change of the reflected light from red to green to blue in rapid succession, thus creating a color display. The core technology of this invention is making the voltage applied to the cholesteric liquid crystal less than the untwisted voltage and still in good focal conic state, that is the symmetric axis are in the same direction, and the pitch is varied according to the voltage applied.
    Type: Grant
